Abstract: A light emitting display apparatus, which turns on a first transistor included in a pixel driving unit and connected to a data line during a data period where a data voltage is supplied from a data driver to the data line, is provided. The light emitting display apparatus includes a light emitting display panel including a pixel including a first transistor connected to a gate line and a data line, a gate driver supplying a gate signal to the first transistor, a data driver supplying a data voltage to the data line, and a switching driver connecting the data line to the data driver or connecting a sensing line to the data driver, wherein the gate driver turns on and then turns off the first transistor during a data period where a data voltage is supplied from the data driver to the data line through the switching driver.
